Tantalum Through-Hole Capacitors – Hermetically Sealed

M55 Module Polymer Hermetic Seal

Reverse Voltage

Solid tantalum polymer capacitors are polar devices and may

be permanently damaged or destroyed if connected with

the wrong polarity. A small reverse voltage is permissible

for time periods per the table at right. KEMET can offer

lower capacitance in this voltage with higher reverse voltage

capability. In addition, we continue to improve our capability

for this characteristic.

Mounting

The M550 and M551 Modular Series are suitable for stacking to the board. The use of a heat sink is recommended.

Theseproductsarenotsuitableforreflowsoldering.Formanual-solderingprocesswithsolderingiron,themaximum

recommended temperature is 350°C for no more than 3 seconds. Care should be taken to avoid contact of the soldering iron

to the epoxy housing. The iron should be used to heat the solder pad, applying solder between the pad and the terminal of

themodule,untilreflowoccurs.
